HARvEsTlNG-MAoHmr-L SPECIFICATION forming part of Letters Patent No. 364,653, dated June 14, 1887.

Application filled July 23, 1884. Serial No. 138,518. (No model.)

following is a specification.

Myinvention has reference to harvestingmachines; and it consists in certain improvements, fully set forth in the followiugspeeitication and shown in the accompanying drawings, which lform part thereof.

The object of my invention is to provide a harvesting-machine with a pivoted hinged iingerbar adapted to be adjusted at any angle desired with the ground, and means whereby its angle with the platform will be automatically changed as the platform is tilted, so that it will always maintain the same angle with the ground, no matter how much the angle of the platform may be varied; further, to so form the machine that the platform is strengthened by a. longitudinal' girder extending entirely across it and through the middle to prevent sagging; further, to support said girder upon the grain and traction wheels, whereby the platform and all appendages may be tipped to any angle desired, or vthe machine may be readily turned or allowed 'to run easily over the ground,being well adapted to accommodate itself to all 4conditions of the earth, the mechanism for accomplishing which objects being described in detail hereinafter.

In the drawings, Figure l is a plan view of a harvesting-machine embodying my improvements. Fig. 2 is a cross-section "of same on line x x. Fig. 3 is a' longitudinal section of same online y y. Fig. 4t is a skeleton perspective view of the girder and framing. Fig.

5 is a perspectiveview of the mechanism for adjusting the finger-bar.' Fig. 6 is an elevation of the outside of the traction-wheel,with part broken away.

A is the longitudinaly girder which extends across the machine, and to which the platform and other appendages of the machine are secured. The outer end of said girder is provided with a journal, A', towhich the grainwheel A2 is journaled, and upon its inner end it is secured to the crank-shaped metal support B, made socket-shaped,as at b', into which the endof the wooden girder A is placed and securely held by bolts. This girder A maybe made of wood or metal, the former being preferred, and, if desired, may be braced by trussrods F. The inner end of support B is provided with bearing B and bracket B2. The shaft and axle D of the traction-wheel C is journaled in said bearing B', whereby said girder A and support B extend from wheel .to wheel and connect them together, allowing are the truss-bars N N, to the outer ends of whieh'are secured the timbers K K', between which the platform is located. The bottom between the timbers K K may be closed by boards le. Between the girder A and each timber K the endless apronsL L are located. These aprons are driven and supported by rollers L. Between the rollers L the'aprons are guided upon rails A4, the center one of which is preferably made of 'a metal plate held down upon the girder A by a strip of wood, A3. If desired, the girder A might be placed vbelow the platform and a single apron extend across the full breadth of the platform.

'The traction-wheel C is formed of a central rim, C', secured to a disk, c,- xed to thhub which is secured to axle D. This disk carries the internal gear, C3.

The gearing for driving the cutter-bar may be constructed as follows: A shaft, G, is j ournaled in the-bracket B2, and carries loosely upon its stubble end a pinion,H,which meshes with the internal gear,C3,within the tractionwheel, `and is providedwith a ratchet-andpawl device, h, the pawl of which is pivoted to a spur-wheel, H2, secured fast to shaft G, and this spur-wheel meshes with a pinion, I, secured to a shaft, I, journaled in the bracket B and carrying'upon its outer end the crankwheel I2,L lwhich actuates the cutter-bar by ,means of a bell-crank lever, M', working on a universal joint between the bars N and N',

the forward end of said lever working in a.

horizontal slot, m, in the casting M, secured to one end of the front timber,K. The shaft shaft O actuates the endless apronsL by the chain and sprocket wheels O.

R is the seat-plank supported over the in- G rotatesa shaft, O, by gearingv O', and said IOO ner end of the platform, and B is the drivers seat. v

The finger-bar l -is pivoted to the platform at J6 Jl. The pivot JG is provided with a crank-arm, J5, and the pivot JT is held in place in the bracket Jg by a nut, J8.

Journaled at a and ai is a rock-shaft, I, having on one end a crank, p, provided with a crank-pin, p', to which a link, P, is hinged, the lower end of which is connected to the pinjaon the crank J5 of the finger-bar. (See Fig. 5.) Secured to this shaft P3 is a lever, I. Loosely `iournaled on shaft P is a sleeve, P', to which a lever, I)2,and the pole I are secured. A brace, P, connects the pole l? also with pin j ou crank P5 by a slot, p, through which the pin passes.

The levers I2 P* extend up over the scat plank R to within reach of the driver, and the position of lever P2 may be regulated and held there by rack-segment Q, secured to the seat-plank It; but lever Bl can only be regu lated to lever I, being secured in position by a segment, Q', carried by lever l. By moving the lever l" the angle of the finger-bar with respect to the ground may bc adjusted, and it will always retain such angle, no matter to what extent the lever I2 may be moved to rock the platform up or down, changing its angle. rlhns if'the finger-barbe adjusted horizontally it will always remain horizontal, no matter how many changes may be given to the angle of the platform. This construction of pivoted finger-bar allows of the platform being pivoted in a line with its center, as there is no possibility of running the fingers or teeth into the ground, and the depth of cut is made practically unlimited and the knives made to cut level.

No reeling mechanism has been shown or described, as any of the devices now in use may be used with this machine.

While I prefer the construction shown,I do not limit myself to the details thereof, as they may be modified in various ways without departing from my invention.

In this application I do not claim the binding mechanism herein shown, for this forms the subject1natter of my application No. 173,947, filed August 10, 1885. Neither do I claim the specific construction of the tractionwheel, the specific conveyor-aprons, nor the eontractiblc rollers, all therein shown.

Having now described my invention, what I claim as new, and desire to secure by Letters Iatent, is-

l. In a harvesting-machine, the combination, with the traction-wheel, its axle, and the platform having a central supporting bar or girder, of a crankshaped support secured at its lower end to the girder and provided at its upper end with a bearing in which the said axle is journaled, and two endless conveyoraprons located on the platform and one on each side of the supporting bar or girder, substantially as and for the purpose specified.

2.
